Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The yard package versions 0.9.19 and earlier are vulnerable to path traversal when the yard server command is used to serve documentation. A remote attacker can send unsanitized HTTP requests to read arbitrary files on the host under certain conditions. Upgrade to yard 0.9.20. Users who cannot upgrade can sanitize HTTP requests at the webserver level, or use the WEBrick server (yard server -s webrick), which sanitizes requests by default.
